摘要： Methods and apparatus for providing consistency in Short Message Service (SMS) timestamp formatting (UTC or non-UTC) for mobile communication devices are disclosed. In one illustrative example, a method involves receiving an SMS message intended for a mobile communication device; identifying whether the SMS message has timestamp data formatted in Coordinated Universal Time (UTC) format or non-UTC format; converting the timestamp data from the UTC format to a non-UTC time format based on an identification that the SMS message has timestamp data formatted in the UTC format; failing to convert the timestamp data to a non-UTC time format based on an identification that the SMS message has timestamp data in the non-UTC format; and causing the SMS message to be sent to the mobile communication device. Other techniques involve mobile device usage of a removable user identity module which has a stored indicator in memory which is indicative of a timestamp mode of operation of a home message center as one of a coordinated universal time (UTC) mode and a non-UTC mode.

摘要： Methods and apparatus for selecting a base station transceiver system for communication with a Third Generation (3G) (or better) mobile station are described. In one illustrative example, one or more base station transceiver systems are identified for communication with the mobile station through a scanning process. A first base station transceiver system is identified as providing a Third Generation (3G) communication service or better, whereas a second base station transceiver system is identified as failing to provide the 3G or better communication service (e.g. it may provide a Second Generation (2G) communication service). The first system is selected for communication over the second system based at least in part on identifying that the second system fails to provide the 3G or better communication service. For example, the first system may be chosen over the second system if the first system has a signal quality that is better than a minimum threshold, even if its signal quality is worse than that of the second system. Advantageously, even if an available 2G system has a better signal quality, preference for an adequate 3G or better system is given to ensure that a preferred data service is made available to the mobile station.

摘要： Methods and apparatus for prioritizing voice call requests during data communication sessions involving a mobile communication device are disclosed. In one illustrative example, an end user invokes a voice call request though a user interface of the mobile device. If this request is made while the mobile device is engaged in a connected data communication service, the mobile device immediately forces the connected data service into a dormant state. In particular, a release order is transmitted to tear down a traffic channel of the connected data service so that the voice call request can be processed. Subsequently, a voice call with the mobile device is established using a new traffic channel. When the voice call is completed, data communications will resume if needed. Advantageously, the mobile device prioritizes voice calls over data communication sessions which may be deemed less time-critical.

摘要： A semiconductor optical amplifier (SOA) apparatus and related methods are described. The SOA comprises a signal waveguide for guiding an optical signal along a signal path, and further comprises one or more laser cavities having a gain medium lying outside the signal waveguide, the gain medium being sufficiently close to the signal waveguide such that, when the gain medium is pumped with an excitation current, the optical signal traveling down the signal waveguide is amplified by an evanescent coupling effect with the laser cavity. When the gain medium is sufficiently pumped to cause lasing action in the laser cavity, gain-clamped amplification of the optical signal is achieved. Additional features relating to segmented laser cavities, separate pumping of laser cavity segments, DFB/DBR gratings, current profiling to improve ASE noise performance, coupled-cavity lasers, avoidance of injection locking effects, manipulation of gain curve peaks, integration with a tunable vertical cavity coupler, integration with a photodetector, integration with an RZ signal modulator, and other described features may be used with the evanescent coupling case or with an SOA having a laser cavity gain medium that is coextensive with the gain medium of the signal waveguide.

摘要： A method and system determine the occupancy status of a room. A computer processor in the system receives a return signal from a RADAR signal emitted into the room. A baseband signal is divided into windows of time. The windows are into an overlapping arrangement wherein some data samples in at least one window are shared by data samples in another window. The data samples in the shifted windows are processed. An output value of the processed data samples is compared to a threshold value. The computer processor determines whether the room is occupied in the event the output value of the processed data samples is greater than or equal to the threshold value. The computer processor determines whether the room is vacant in the event the output value of the processed data samples is less than the threshold value.
